Abstract

During methane hydrate-bearing sediments (MHBS) extraction multiphase flow with heat transfer transitioning MHBS phase followed by pore dynamic evolution. Which involves a complex thermo-hydrodynamic (THC) coupled process. Effective theoretical and fully integrated numerical models are essential for evaluating the economic feasibility of gas hydrate production and comprehending the fundamental physical concepts. This study presents a novel approach to constructing a fully integrated THC numerical model by employing a peridynamic differential operator (PDDO). The dimensionless governing equations of Darcy’s law and the heat source approach are transformed into a non-local integral form. The Euler forward difference method is used for time integration. The accuracy and reliability of the newly developed PDDO THC model were tested by comparing it with experimental examples from other popular simulators, which provides an alternative to explicit modeling of the phase change process involving multiphase flow with heat transfer and may find comprehensive and useful applications to a variety of industrial and geophysical processes.

期刊介绍： The use of computers is firmly established in geotechnical engineering and continues to grow rapidly in both engineering practice and academe. The development of advanced numerical techniques and constitutive modeling, in conjunction with rapid developments in computer hardware, enables problems to be tackled that were unthinkable even a few years ago. Computers and Geotechnics provides an up-to-date reference for engineers and researchers engaged in computer aided analysis and research in geotechnical engineering. The journal is intended for an expeditious dissemination of advanced computer applications across a broad range of geotechnical topics. Contributions on advances in numerical algorithms, computer implementation of new constitutive models and probabilistic methods are especially encouraged.
